To all whom it may concern:

Be it known that I, HANS M.. Orson, a citizen of the United States, residing at Beaumont, in the county of Riverside and State of California, have invented a new and useful Improvement in aWaterproof of which the 'following is a' specification.

This invention relates to compositions of matter technically called concrete, and its principal object 18 to provide greater tensile strength and toughness to concrete structures as formed from cement, namely aggregate and a mixing medium.

It is also an object to provide a concrete that will be'water roof. 4

It is a further ob ect to provide an emulsion to be used to mix with the dry concrete.

- Heretofore concrete has been formed from a mixture of Portland on other cement mixed with sand, gravel stone or other aggregate in different proportions to which has been addedwater till the mixture has been properly incorporated, and then al-' lowed to cure. The curingprocess requires an unusual amount of skill on the part of the attendant, and the result obtained under the best treatment, which would require entire immersion in water many hours, results in a structure that isporous enough to absorb or permit water to pass through with little tensile strength and liable o fail or crack from the compression strain. 7

This invention overcomes vthe objections as above described, inthat' the concrete mixed according to the rocess'and with the ingredients described "ereatter requires but slight attention-,and the resulting prod; uct has greater tensile strength, is tough and will not fail or crack as the ordinary concrete. I I i Carrying out the invention, an emulsion is first formed consisting oflime which is started on its slaking process by the addition of a suflicient quantity of water. When considerable heat has developed by the slaking recess, a heavy oil is added, preferably cm o petroleum, as this latter is more 000- nomical, until the lime is slakened and will not take'u an more oil.

Should t e s aking process become overheated or liable to burn, morewater must be addedto prevent the burning; When the] flaking process is complete, the emulsion is Specification of letters Patent. Application med August ae,'1912. Serial No. 716,984;

for use. The proportions required are from t is composition are Patented Sept. 1, 19.14.

allowed to cool, and if necessary, a suflicient amount of water is added to thin the mixture to the desiredconsistenoy which'is alittle less than that of cream; The emulsion is then strained to remove any lum s that may have formed, and is now rea y proximately, ten pounds of lime during slaking will take up about one gallon of crude petroleum and one and a half gallons 0. water. The emulsion formed results in dividing the oil into practically imperceptible particles which are separated from contact with the cement by a coating of the lime, and do not interfere with the settin or hardening of the concrete. 7 These partic es of oil fill up the voids in the struc I ture, and cement the entire ingredients into a solid homogeneous mass.

Thedry concrete is now mixed. in the proportions desired depending upon the class of the structure to be'built, consisting usually. of cement,

sand vel' or stone thoroughly mixed. To this dry concrete the emulsion is added-in the well known manner as water thoroughly mixed until the required consistency] is obtained. A mixture of this character is especially effective for water irrigating pipes, the resulting structure having the same efliciency of iron pipe or the same character, and will not require any dipping to withstand pressure. The emulsion 'also retards. the efiects of the moisture and-the composition-will cure ,perfectly without being immersed in water, and'with very l-ittle or no sprinkling.

Shin les, building blocks tough, will not crack and are waterproof withoutnny ad ditional process, none'aof which heretofore have been able to entirely render the concrete impervious to water.

What I claim is: p The herein-described composition oi matter consistip 'g of lime, ten pounds, crude .oil one gallon and water.
